CHP1 Pyrheliometer

The CHP1 pyrheliometer is the most commonly used radiometer for the measurement of direct normal irradiance (DNI) and offers high accuracy and reliability.

CHP1 fully complies with the most current ISO and WMO performance criteria for First Class Normal Incidence Pyrheliometer. Every CHP1 is calibrated upon manufacture, and is supplied standard with a WRR (World Radiometric Reference) traceable calibration certificate.

The CHP1 is fitted with a high quality connector for easy installation and maintenance. The screw-in drying cartridge is easy to remove and the replacement desiccant is supplied in convenient refill packets.

As standard CHP1 come with both Pt-100 and 10k thermistor temperature sensors.

The instrument covers the total solar spectrum between 200 to 4000 nm. CHP1 is intended for use with any model Kipp & Zonen two-axis Tracker.

The CHP1 is the perfect choice for high accuracy direct solar radiation measurements.
